am I making something out of nothing?

Ok so I've been off the pill for a while now and me and my partner have been having unprotected sex, about a week ago we had unprotected sex while I was ovulating and the past 4 or 5 days I haven't been able to shake this constant feeling of needing to throw up! got to the point yesterday where I had to call in sick because I kept throwing up every few hours! and i keep getting cramps which is normal for me at this stage in my cycle like i always get them around this time but today I noticed a little spotting when I wiped. is there a chance these could be early pregnancy symptoms or am i just being super hopeful 😅
